+### Text emphasis restriction to single-lines
+
+By default text emphasis works across multiple lines until a closing token is found. However, it's possible to restrict text emphasis to a single line (ie, for it to be applied a closing token must be found on the same line). To do so:
+
+```vim
+let g:vim_markdown_emphasis_multiline = 0

 For example, conceal `[link text](link url)` as just `link text`.

 For example, conceal `[link text](link url)` as just `link text`.

+Also, `_italic_` and `*italic*` will conceal to just _italic_.

+will conceal to just __bold__, **bold**, ___italic bold___, and ***italic bold*** respectively.

+
+### Fenced code block languages
+
+You can use filetype name as fenced code block languages for syntax highlighting.
+If you want to use different name from filetype, you can add it in your `.vimrc` like so:
+
+```vim
+let g:vim_markdown_fenced_languages = ['csharp=cs']
+```
+
+This will cause the following to be highlighted using the `cs` filetype syntax.
+
+    ```csharp
+    ...
+    ```
+
+Default is `['c++=cpp', 'viml=vim', 'bash=sh', 'ini=dosini']`.
+
+### Follow named anchors
+
+This feature allows ge to follow named anchors in links of the form
+`file#anchor` or just `#anchor`, where file may omit the `.md` extension as
+usual. Two variables control its operation:
+
+```vim
+let g:vim_markdown_follow_anchor = 1
+```
+
+This tells vim-markdown whether to attempt to follow a named anchor in a link or
+not. When it is 1, and only if a link can be split in two parts by the pattern
+'#', then the first part is interpreted as the file and the second one as the
+named anchor. This also includes urls of the form `#anchor`, for which the first
+part is considered empty, meaning that the target file is the current one. After
+the file is opened, the anchor will be searched.
+
+Default is `0`.
+
+```vim
+let g:vim_markdown_anchorexpr = "'<<'.v:anchor.'>>'"
+```
+
+This expression will be evaluated substituting `v:anchor` with a quoted string
+that contains the anchor to visit. The result of the evaluation will become the
+real anchor to search in the target file. This is useful in order to convert
+anchors of the form, say, `my-section-title` to searches of the form `My Section
+Title` or `<<my-section-title>>`.
+
+Default is `''`.
+

+### Adjust new list item indent
+
+You can adjust a new list indent. For example, you insert a single line like below:
+
+```
+* item1
+```
+
+Then if you type `o` to insert new line in vim and type `* item2`, the result will be:
+
+```
+* item1
+    * item2
+```
+
+vim-markdown automatically insert the indent. By default, the number of spaces of indent is 4. If you'd like to change the number as 2, just write:
+
+```vim
+let g:vim_markdown_new_list_item_indent = 2
+```
+
+### Do not require .md extensions for Markdown links
+
+If you want to have a link like this `[link text](link-url)` and follow it for editing in vim using the "ge" command, but have it open the file "link-url.md" instead of the file "link-url", then use this option:
+
+```vim
+let g:vim_markdown_no_extensions_in_markdown = 1
+```
+This is super useful for GitLab and GitHub wiki repositories.
+
+Normal behaviour would be that vim-markup required you to do this `[link text](link-url.md)`, but this is not how the Gitlab and GitHub wiki repositories work. So this option adds some consistency between the two. 
+
+### Auto-write when following link
+
+If you follow a link like this `[link text](link-url)` using the "ge" shortcut, this option will automatically save any edits you made before moving you:
+
+```vim
+let g:vim_markdown_autowrite = 1
+```
